WILLIAM H. FERGUSON, OF DENVER, COLORADO, ASSIGNOR OF ONE-HALF TO JOHNA. FERGUSON, OF DENVER, COLORADO.

COMBINED CURB AND GUTTER.

SPECIFICATION forming part of Letters Patent No. 728,693, dated May 19,1903.

Application filed January 8, 1903. Serial No. 138,301. (No modeLl To allwhom, t nuty concern:

Beit known that I, WILLIAM H. FERGUSON, a citizen of the UnitedStates,residing at Denver, in the county of Denver and State ofColorado, have invented new and useful Improvelments in a Combined Ourband Gutter, of which the following is a specification.

My invention relates to street-curbing; and it consists in the combinedcurb andgutter and lo the combined curb and gutter block hereinafterdescribed, and particularly pointed out in the claims appended.

In the accompanying drawings, Figure 1 is a transverse section of myimproved combined curb and gutter, taken in the plane indicated by theline l l of Fig. 2; Fig. 2, a plan of the same, and Fig. 3 a perspectiveview of one of the blocks of which the combinedcu rb and gutter isformed.

Similar letters of reference designate corresponding parts in all ofthe-viewsof the drawings, referring to which- A is a street; B, asidewalk of bricks or other suitable material a, laid on earth,concrete, or other suitable material b, and O myr improved combined curband gutter. The latler is formed of blocks D of concrete, burnt clay, orother suitable material laid end to end in a bed of cement or the likeand joined 3o by cement or other suitable means. .The

blocks D are similar in constructiomaud therefore a detailed descriptionof the one shown in Fig. 3 will suffice to impart an understanding ofall. Said block, which may be molded or formed in any other suitablemanner, coniprises a horizontal portion c, designed to rest flush withthe surface of the street A, Fig. l, and a vertical portion d of greaterthickness than the horizontal portion, said vertical portion beingdesigned to rest fiush with the surface of the pavement B and having oneor a plurality of cavities e. in its side adjacent to the same for apurpose presently described. When desired, an angular metallicreinforcement E, preferably an angular iiuted plate, may be embedded inthe block, Figs. 1 and 3, withaview ofstrengthening thejoint between thehorizontal portion c and the vertical portion d. I desire it distinctlyunderstood, how- 5o ever, that the block may bemade without the saidreinforcement without involving a departure from the scope of myinvention.

In laying my improved curb and gutter the blocks D are arranged end toend in the bed of cement in such position that the upper sides ot' theportions c are liush with the surface of thestreet A, after which theearth, concrete, or other material b is rammed into 'the cavities e andthe surface ot of the sidewalk is made iiush with the upper side of the6o portions d.

It will be observed that in virtue of the earth or other material bbelow the surface of the sidewalk being rammed into the cavities e ofthe blocks D the said blocks will be held to the sidewalk and at thesame time their vertical portions d will be supported and enabled towithstand the blows to which curbs are ordinarily subjected. It willalso be observed that the cavities e in the vertical por- 7o tions d ofthe blocks are advantageous because of the saving in t'he material ofwhich the blocks are formed and also because they render the blockslight, and consequently lessen the cost of shipping the blocks fromplace to place.

Having described my invention, what I claim, and desire to secure byLetters Patent, 1s-

1. As an improved article of manufacture, So a combined curb and gutterblock comprisingv a horizontal portion, and a Vertical portion, integralwith the horizontal portion, and having one or more cavities e in itsvertical side remote from the horizontal portion; said cavity orcavities being open at but one side.

2. As an improved article of manufacture,

a combined curb and gutter block formed of concrete or other suitablematerial and comprising integral horizontal and vertical por- 9o tions;the vertical portion being of a greater thickness than the horizontalportion,and having one or more cavities in its vertical side remote fromthe horizontal portion, and an angular, metallic reinforcement embeddedin the horizontal and vertical portions.

3. As an improved article of manufacture,

a combined curb andgutter block formed of concrete or other suitablematerial and comprising integral horizontal and vertical porroo remotefrom the horizontal portion, and an angular, metallic reinforcementembedded in the horizontal and vertical portions.

In testimony whereof I have hereunto set 15 my hand in presence of Iwosubscribing witmesses.
